Five new species of the genus Leucania Ochsenheimer in Central America (Lepidoptera: Noctuidae).

Five new species of the noctuid genus Leucania in Central America are described: L. mopan Adams and McCabe, sp. nov., L. merga Adams and McCabe, sp. nov., L. championi Adams and McCabe, sp. nov., L. colorada McCabe and Adams, sp. nov., L. sororia McCabe and Adams, sp. nov. The internal genitalia are key to resolving the taxonomy in this genus; in particular, the morphology of the male everted endophallus (vesica) and the female bursa copulatrix jointly resolve taxonomic confusion among cryptic species near L. albifasciata, L. oaxacana and L. humidicola. We recognize the valvular pore plate and the "poma" (bubble-like structure at base of valvae) as generic synapomorphies for Leucania. Lappets (inflatable pouches on the outer aspect of the valvae) are newly described. Descriptions and color illustrations of the imagos, male valvae, everted endophalli, and the female bursae copulatrix are provided for all newly described species and selected congeners to aid identification. Additional nomenclatorial actions are: Leucania complicata Strecker, 1898 rest. stat.; Leucania februalis Hill, 1924 syn. nov., a junior synonym of L. humidicola; Leucania elephas Troubridge 2020 syn. nov., a junior synonym of L. humidicola.

A REVISION OF THE NEW WORLD MOTH GENUS ATHYRMA HBNER (LEPIDOPTERA: EREBIDAE).

The genus Athyrma Hbner, [1823] 1816 is revised, with a generic re-description and transcriptions of original descriptions (with translations) of all described species provided. Sixteen Athyrma species are recognized in this paper. Nine species are new: A. brigittae Adams McCabe sp. nov., A. tapichensis Adams McCabe, sp. nov., A. urbanae Adams McCabe, sp. nov., A. yasuni Adams McCabe, sp. nov., A. ciboney McCabe Adams, sp. nov., A. cryani McCabe Adams, sp. nov., A. itatiaia McCabe Adams, sp. nov., A. romacki McCabe Adams, sp. nov., and A. svensoni McCabe Adams, sp. nov. Taxonomic changes are as follows: Athyrma antica Schaus, 1912, syn. nov., a junior synonym of A. nodosa; A. cunesema Hampson, 1926, syn. nov., a junior synonym of A. cunesema; Athyrma cordigera Walker, 1869, comb. nov., syn. nov., a junior synonym of Celiptera levina Stoll, 1781. A lectotype is designated for A. adjutrix (Cramer, 1780). Neotypes are designated for four species: Athyrma nodosa Mschler, 1880, A. orbana Mschler, 1880, A. tuberosa (Felder and Rogenhofer, 1874), and A. ganglio Hbner, [1831] 1825. Athyrma ganglio Hbner, [1831] 1825, rest. stat. and A. dormitrix Guene in Boisduval and Guene, 1852, rest. stat. are removed from synonymy and restored as valid species. Athyrma has been associated with the Eulepidotinae however is here tentatively assigned to Erebinae: Poaphilini because of its similarity to Mimophisma Hampson, 1926. Illustrations of male and female adult habitus, ultimate instar larva, dissections of male and female external and internal genitalia are provided. Athyrma misera Butler, 1879 is removed from Athyrma and placed in Ezra gen. nov. Nymbis resecta Dognin, 1912 is removed from its current placement in Athyrma and placed in Facies gen. nov. Checklists of all three genera are provided.

The identity of Arhodia egenaria Walker, 1866 (Lepidoptera, Mimallonoidea, Mimallonidae) and a new synonym of Cicinnus melsheimeri (Harris, 1841).

The holotypes of Arhodia egenaria Walker, 1866 and Cicinnus primolus Schaus, 1928, syn. n., were examined. Both names are junior synonyms of C. melsheimeri (Harris, 1841). Cicinnus melsheimeri (as Perophora egenaria), sensu Hampson, 1904, is a misidentification of C. bahamensis St Laurent & McCabe, 2016.

The Mimallonidae (Lepidoptera, Mimallonoidea) of the Caribbean Basin, with the descriptions of two new species.

Mimallonidae of the Caribbean Basin are discussed, with attention primarily given to species endemic to the Caribbean islands and the northern coast of Venezuela. The Caribbean Basin is a political term for tropical regions circumscribed by the Gulf of Mexico. Cicinnus bahamensis sp. n. is described from the Bahamas, the first species of Mimallonidae from this country. The Cuban species Cicinnus packardii (Grote, 1865), the closest relative of C. bahamensis sp. n., is figured and compared. A third, similar, species from northern coastal Venezuela, C. falcoargenteus sp. n., is described and compared to the previous two species.

A new Zanclognatha from eastern North America and a preliminary key to the larvae of the genus (Lepidoptera, Erebidae, Herminiinae).

The adult of a widespread but previously undescribed species of Zanclognatha Lederer is described from eastern North America. Images of the mature larva and life history datafor Zanclognathadentatasp. n. are included, along with a preliminary key to the larvae of ten eastern North American Zanclognatha species.
